长尾山雀研究 Black- and Silver-throated Tit Project
最早在2006年,我们在河南董寨国家级自然保护区开展对白冠长尾雉的野外研究时,注意到红头长尾山雀繁殖的时候有多只成鸟带着一群出飞雏鸟,因此怀疑红头长尾山雀有合作繁殖行为。2007年,我们进一步关注长尾山雀的繁殖,并确认了其帮手行为的存在。2008开始,我们正式开始了对长尾山雀的研究。由于在董寨自然保护区,红头长尾山雀和银喉长尾山雀同域分布,所以从一开始我们便对两种长尾山雀开展同步研究,试图从进化的角度解释它们的生活史和繁殖策略。我们的主要研究地点在董寨国家级自然保护区的白云保护站,但我们有时也到其它保护站开展调查工作。目前,我们的主要工作涉及两种长尾山雀的合作繁殖行为发生的规律、亲鸟和帮手的繁殖投入、合作繁殖的利益和代价等,以及长尾山雀的配偶选择、亲代对后代的性比调控;繁殖策略的季节性变化等。 从2011年起,我们的研究项目获得“两种长尾山雀合作繁殖行为发生的规律及机制研究(项目批准号:31101644)”、“两种长尾山雀的配对模式和后代性别分配的影响因素研究(项目批准号:31472011)”、“亲缘选择在两种长尾山雀合作繁殖行为中的作用及一种可能机制的探讨(项目批准号:31970421)”三项国家自然科学基金项目的资助。
In 2006 when we were studying the Reeves's Pheasants in the Dongzhai National Nature Reserve, we noticed that there were several adult Black-throated Tits accompanying the young fledglings. This made us to speculate that they might be cooperative breeders. Then in 2007, we spent more attention to the breeding of the tits and cofirmed the existence of helping behaviour in the Black-throated Tits. In 2008, we formally started our study of the tits. As both Black-throated Tits and Silver-throated Tits are distributed in Dongzhai, we have been studying them simultaneously at the very beginning of the study. Our main study area is at the Baiyun Station of the reserve and adjacent areas, but our work also occasionally extends to other areas of the reserve. Currently, we primarily focus on questions like the occurrence rhythm, costs and benefits of the cooperative breeding behavior, investment strategies of the breeders and helpers, the mate choice and offspring sex allocation, seasonal change of the reproductive strategy, etc. Since 2011, our studies have received financial support of three projects from National Natural Science Foundation of China (No. 31101644; No. 31472011;No. 31970421).
